Abstract (en)
[origin: EP3614443A1] The present application relates to a densely-arranged solar cell string and a preparation method thereof, a solar cell module and a solar cell system. The preparation method of the present application mainly comprises the following steps: preparing a solar cell, and forming H-type electrodes on front and back surfaces of the cell, wherein main grids are segmented electrodes and welding points are arranged at ends of the main grids; printing a strip-shaped hot melt adhesive at the welding points in a direction perpendicular to the main grids, and exposing the welding points from the hot melt adhesive; cutting, along a cell cutting region, the cell into a plurality of small cells; coating an conductive adhesive or solder paste at the main grid welding points on front surfaces of the small cells; superposing main grid welding points on a back surface of one small cell onto main grid welding points on a front surface of another small cell, and heating so that the two small cells are electrically connected through the conductive adhesive or solder paste; and, successively connecting the plurality of small cells to form a solar cell string. The present application has the following beneficial effects: the utilization area of cells in an effective region of a module is increased, and the power of the module is improved.
